我正在尝试安装 Cisco 的 Packet Tracer 以便在 Ubuntu 16.04 上进行一些培训，我完成了安装过程，但是当我运行它时，我得到：
$ ./PacketTracer7
Segmentation fault (core dumped)
现在我通常会在提问之前尽可能多地用 Google 搜索，但关于这个主题的搜索结果并不多，而且这个错误实际上并没有提供太多关于出了什么问题的信息。
我决定检查一下所需的软件包，目前看来一切都顺利：

任何帮助都将不胜感激！
答案1
找一个解决方案在这里：
由于应用程序文件夹和系统中的 QT 版本混合存在问题，因此这种方法使 packettracer 主要使用系统库。
假设默认安装目录 /opt/pt
1-创建一个目录，调用libwebkit并将packettracer的所有libqtwebkit复制到该目录或
$ sudo mkdir /opt/pt/libwebkit
$ sudo cp /opt/pt/lib/libQtWebKit.so* /opt/pt/libwebkit/
2-然后使用以下命令运行 packettracer
$ LD_LIBRARY_PATH=/opt/pt/libwebkit/ /opt/pt/bin/PacketTracer7
谢谢达拉·西姆
3-所以你必须编辑初始化脚本/opt/pt/packettracer更改为：
#!/bin/bash
echo Starting Packet Tracer 7.0
PTDIR=/opt/pt
export LD_LIBRARY_PATH=$PTDIR/libwebkit/
pushd $PTDIR/bin > /dev/null
./PacketTracer7 "$@" > /dev/null 2>&1
popd > /dev/null
答案2
您需要运行启动脚本“packettracer”以便使用打包的库。
